METAL BEns'rnan.

Specification of Letters Patent.

Patented Feb. 4, 1913.

' Application filed June 21, 1911. Serial No. 634,507.

To all whom it may concern Be it known that I, JOHN.M. ADAMS, a citizen of the United States, and a'resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Metal Bedsteads, of

which the following is a specification.

This invention relates to metal bedsteads and relates particularly to corner fastenings for such beds.

The 'object of the present invention is to provide improved means for detachably se-- curing corner fastening members to the posts of metal bedsteads, constructed and arranged to prevent accidental loosening of said corner fastening members, in use.

To this end, my invention comprises the various features and details of construction hereinafter described and claimed.

.In the accompanying drawing, in which my invention fully illustrated, Figure 1 is a fragmentary,longitudinal sectional view of thepost of a metal bedstead, showing a corner fastening secured thereto in accordance with my invention. Fig. 2 is a sectional view thereof, on the line 2'-2 of Fig. 1; and Fig. 3 is a perspective view of the wedge forming part of my improved securing means.

Referring now to the drawings, l'designates a post of a metal bedstead, said post being hollow in accordance with the usual construction, and 2 is a corner fastening member secured to said post, being usually made of'cast iron. The means for securing said corner fastening member 2 to thepost 1 comprises an eye 3-on said corner fastening member 2 which projects from the face of said corner fastening member which abuts against the post 1 and extends through a slot 4 formed in said post to receive the same. As shown, said eye 3 is formed by a staple the ends 5 of which are anchored in the corner fastening member 2.

Inserted through the eye 3 inside of the post 1, is a wedge '6, formed in the side thereof which bears against said post, is a recess 7 the bottom 8 of which is inclined lengthwise of said wedge, diverging from the side or face of said wedge which bears against the post toward the larger or head end of said wedge. hole in the post- 1 is a screw 9 the end of which bears against the inclined surface 8 on the wedge 6, said screw being inserted after the wedge is in position.

Threaded through a With the described construction, it is obvious that the screw 9 will lock the wedgeagainst endwise movement tending to loosen or disengage the same from the eye 3, while the pressure of the wedge'will, in turn, prevent turning and loosening of the locking screw 9.

While I have herein shown the inclined surface'8 as formed at the bottom of-the recess .7, I do not desire to limit myself to this specific construction, as said inclined. sztrface may be formed in any position and 1' lation desired, within the scope of my invent-ion. Beyond the inclined surface 8, the face of the wedge 6 which bears against/the post is grooved between its'edges, as shown at 10, leaving longitudinal marginal bearing surfaces. This is merely to avoid fitting and dressing, and forms no part of my present invention.

I claim-:-' I .1. In a metal bedstead, a hollow post, a

corner fastening member, means 'for secur-- ing said corner fastening member to said.

post, said means comprising an eye on said corner fastening member which projects through a slot formed in said post, a wedge inserted through said eye inside of said post, and means to prevent loosening of said wedge, said means comprising an inclined surface on said wedge other than a I wedging surface thereof, and a screw threaded through said post the end of which bears against said other inclined surface on said wedge, substantially .as described.

2. In a metal bedstead, a hollow post, a corner fastening'member, means for securing said corner fastening member to said post, said means comprising an eye on said corner fastening member which projects througha slot formed in said post, a wedge inserted through said eye inside of said post and means to prevent loosening of said wedge, said means-comprising an inset inclined surface on said wedge otherthan a wedging surface thereof, and a screw threaded through said post the end of which bears against said other inclined-surface on said wedge, substantially as described.

3. A hollow first member provided with a slot, a second member and means for secur-.

ing said second member to said hollow'first member, said means comprising an eye on said second member which projects through the'slot in said hollow first member, a wedge inserted through said eye inside of said h llow first member, and means to prevent 1n testimony, that l claim the foregoing loosening of said Wedge, said means eemus my invention, ll efix my signature in 1a prising an inclined surface on said wedge presence of tWo subscribing Witnesses, this other than a Wedging surface thereof, and e 19th day of June, A. 11.1911.
